STOVE.

SPECIFICATIONforming part of Letters Patent No. 366,926, dated July 19, 1887. Application filed February 9, 1887. Serial No. $227,040. (No model.)

To all whom, it may concern.-

'Be it known that I, Tiroirns CAswELL, a citizen of the United States of America, residing at Cherokee, in the county of Cherokee, in the State of Iowa, have invented a new and useful Improvement in Hot-Air Stoves, of which the following is a specification.

My invention has relation to improvements in means for utilizing the interior parts of stoves for distributing hot air in the compartments; and my invention consists in a globular hot-air chamber sustained within the rechamber ofa stove by means of conductingpipes let through the shell of the stove, and having a cold-air pipe opening` into the globe from below.

I have fully illustrated my invention in the accompanying drawing as applied to a parlor self-feeding stove, wherein is given a view, partly in section, of a stove with my hot-air chamber applied, the shell of the stove being broken away in'parts to show the same more fully.

Reference being had to the drawing, the letter A designates the stove, of approved style, consisting` of the base l, combustionehamber 2, having the damper-space 3, and the top 4, having the feed-reservoir 5 secured therein. Since these may be of any of the approved const-ructions, and are generally wellknown, no other or further description of them is deemed essential to the proper application of my invention.

Theletter B designates my improved hotair cham ber. This consistsofaglobular chamber, 6, preferably having a conical upper for mation, 7, intended to set under the delivery end ofthe magazine of the stove, the cone being designed to letv the dropping coal separate and be distributed about the hotair chamber in' the combustion-chamber of the stove. The hot-airchainberis arranged in the combustionehamber so as to leave sufficient space between its surface and the shell of the stove to warrant a quantity of fuel, enough to burn freely and yet keep combustion up. From the upper surface of the hot-ai r chamber are projected two or more hot-air pipes, 8, which open from the chamber and are extended and have their open outer ends secu red to the shell of the stove to register with the apertures a, formed in the shell of the stove above the firepot, substantially as seen in the drawing. From the bottom part of the hot-ai r chamber is led downward the cold-air pipe 9, preferably carried from the bottom of the chamber across the combustion-chamber through the shell of the stove, enlarged and carried down to the bottom flange of the base of the stove, as seen at 10. It will thus be seen that the hotair chamber is sustained by the ends of the hot-air pipes in conjunction with the coldair pipe. By my invention the caloriceffects of the interior combustion of the fuel are fully and completely utilized in heating the eo1npartment, and at the same time agreat saving of fuel is obtained.

It may be requisite and necessary to make the combustion-chamber of the stove to which myinvention is applied broader than ordinary, in order to get the full benefit of my invention and afford the space desired for steady, durable, and complete combustion; but such construction will be perceived by those skilled in the art.

"What I claim as my invention, and desire to secure by Letters Patent, is-

The combination, with the shell ofa heatingstove, A, formed with apertures (t, of a globular hot-air chamber set in the combustionchamber and under the magazine of the stove, and formed with two or more hot-air pipes projected from the upper part of the hotair chamber in opposite directions, said pipes having` their outer ends fastened to the shell to register with the said apertures ofthe stove,and a coldair pipe opening into the bottom of the hot-air chamber and led across the bottom of the combustionchamber, and thence down the inner side of the shell of the base ofthe stove, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
